Kaltman Debuts PC-Based RF Spectrum Analyzer With White Space Finder
Kaltman Creations has introduced a series of PC-based RF spectrum analyzers it says are designed for the pro audio and video industries.

Called Invisible Waves, the analyzers automatically chart open RF frequencies, for use with wireless microphones, in-ear monitors and remote control.

The first in the series is the Invisible Waves model IW1800, which covers the frequency span of 100 kHz to 1.8 GHz, making it suitable for VHF and UHF analysis and extending into the lower gigahertz ranges.

According to the company, future models will include the Invisible Waves model IW4000, which covers the span of 100 kHz to 4 GHz; and the IW7000, covering the frequency span of 100 kHz to 7 GHz. Resolution bandwidth (RBW) in all models is 1 kHz with a typical sensitivity of –120 dBm.

“We sat down with a focus group of professional audio engineers and AV integrators, and asked what they needed in a RF spectrum analyzer to help overcome the current and impending wireless ‘crunch,’” said President Mark Kaltman. He said their first response was the ability to find open space for frequency and channels selection followed by the ability to identify and locate interference.

“Other items of importance included ease of use, logging and reporting capabilities, portability, and of course, affordability,” he said. The IW1800 kit retails for $1,495.

The Invisible Waves analyzers have an Automatic White Space Finder that identifies open RF space within a user-defined range. The White Space Finder also graphically depicts the ideal positioning of the transmitters within the given open space.

The analyzers are sold as kits that include a built-in rechargeable battery pack, AC adaptor/charger, multiple antennas and a USB-to-PC connection, enclosed in a pre-configured, laptop-sized carrying case.
